VULCANIZER.

' and tires, it will be apparent as the description'proceeds that theinvention is not limited to the precise form shown. l

The object of the invention is to provide a Avulcanizer in which theplate or equivalent device which supplies heat tothe ru'bber to bevulcanized, is so mounted with respect to the parts adjacent and whichsupport it that the heat is confined to this plate, thus conserving theheat and further preventing the adjacent parts of the v'ulcanizerfrombecomin highly heated.

A urther object of the invention is to provide a vulcanizer in which adefinite quantity of heat, if we may term it that, is applied in theJheating of the vulcanizing plate. v

Generally speaking, the invention may be said to comprise the elementsand combinations thereof set forth inthe accompanying claims.

Reference should be had to the accompanying drawings forming a part ofthis specification, in which Figure l is a side elevation ofthe'vulcanizer; Fig.' 2 is a rear elevation of the vulcanizer; Fig. 3 isan elevation with portions of the vulcanizer in section; and Fig. 4 is atransverse section through portions of the device.

The base of the vulcanizer is generally represented at 1. This base isprovided with feet, such as are represented at 2, which permit the baseto be laid hat upon a surface when the material to be vulcanized isarranged and placed in the vulcanizer.

The base has extending therefrom an arm 3 upon which is pivoted a lever4. This 'lever is provided with a slight foot extension 4*l so that thevulcanizer. may be supported in the position shown in Fig. 1. .Thisposition of the vulcanizer is desirable inasmuch as in vulcanizing suchan article as an inner tune of a tire itis desirable to so place thisSpecication of Letters Patent.

tube thatit will not be in'danger of being burned, or even unduly heatedby contact with any part of the vulcanizer structure which may becomeheated as the vulcanizer is operated. The position of the Vulcanizer 'asshown in Fig. l 4 permits the tube to be drawn back and away from thebase 1 and the'parts adjacent thereto.

The end of the lever 4 is provided with a depressed portion having arounded surface as indicated at 5. This depressed portion coperates witha cam-shaped member 6 having a handle 7 The cam-shaped member haspivoted to it a strap 8.which is of a U-shape and straddles the lever 4at the end thereof, as well as the cam-shaped member 6. The strap ispivoted as indicated at 6a being eccentric with respect to the centerpoint of the cam-shaped member 6.

The strap 8 is secured at one end of a' spring 9, this spring at itsopposite end be.

ing secured to an extension 10 whichl is carried by the base. When thecam-shaped member 6 is in the position shown in Fig. 1 the spring 9 isunder tension and the lever 4 is held by the arrangement of elementswhich have been described.

The lever 5 between the ends thereof is provided with al1-inwardextension 11. This extension coperates with a presser plate member 12.This member 12 is provided with a depression 12a with which theprojection 11 cooperates.

The base 1 is provided with an opening 13. Through this openin thereextend portions of a hotplate mem er which is generally represented at14. This hot plate member consists of a plate proper l5 from whichextend pins or fins 16. These parts 16 extend through the opening 13 ina manner indicated in'. Fig. 3. The plate 15 is heat insulated from theportion of the ,base 1 upon which it rests by means of washer members 17which are made of any suitable heatlv insulating material. The opening13 through.

heat thus applied to these members will be conducted directly to theplate proper 15, and from this plate conducted to the article heati tobe vulcanized, which in the instance shown is an inner tube for a tire,as indicated at 18, to which a patch indicated at 19 is to bevulcanized. Applying the heat to the fins or pins 16 insures that theheat is directly given to the hot plate 15, and in fact the structurethus heated' is heat insulated from the restl of the structurecomprising the vulcanizer, and insures the conlining of nearly all ofthe `heat to the hot plate and prevents the dissipation of the heatthrough the structure of the vulcanizer.

This overcomes a great objection, for in .manyl types of smallvulcanizers theheat dissipates through the vulcanizer body the same,which uct only wastes heat, ut heats .the metal structure of thevulcanizer to such an extent that if the tube or rubber article beingvulcanized comes ito contact with the metal parts of the Vulcanizer, thetube is burned,.and some times-so injured as to destroy the tube. A

By insulating the heating plate 15 the surrounding parts of thevulcanizer structure willnever become so hot as to damage the tube ifperchance it should come in contact with it.

The body or base 1 isprovided lwith a.

pocket portion 1a as indicated in Fig. 3. This body portion is adaptedto receive a heat supplying device which preferably is a heating unit orcartridge 21. This heating unit or' cartridge is prepared by inclos-ving a combustible material within a. suitable container which Ipreservesthe combustible material` against dissipation until such time yas partor all of the containing wrapper is removed vfor the purpose of ignitingthe combustible material.

The quantity of combustible material comprising -a cartridge 'is adefinitely ascertained lquantity which will liame up around the pins 16and supply the requisite amount of heat to the pins or fins 16, andthence to the hot plate 15, tofefect the proper vulcan'ization of thearticle being vulcanized. For instance, it ,can be definitelyascertained the proper time that heat should be applied to such a tubeas the tube 18 when it is desired to vulcanize such a patch as 19 tothetube.

This time of heating being ascertained the .quantity of combustiblematerial comprising the cartridge 21 can be determined.

Therefore, if such a cartridgeas 21 be used each time it is desired tovulcanize a patch to a tube, the requisite amount of heat, for theproper length of time can be applied to the patch and tube, and thusinsure a proper vulcanizing without danger of overheating the patch andtube.

A cover 25, having resilient prongs may be utilized .to'inclose thespace occupied by the Haine from the heat supplying means. This cover isreadily removable.

It will be apparentv that various details lingers, a presser plate, andmeans for holdlng said presser plate in proper position with respect tothe hot plate.
